Key legal question
Whether the cantonal remand decision was separately appealable only for the period up to 31 January 2009.
Extracted holding
Only the part finally deciding the pension entitlement until 31 January 2009 was an appealable partial decision; the remand for the later period was an unappealable interim decision.
Extracted reasoning
A remand decision is normally interim; the final ruling concerns only the period finally adjudicated on the merits, which may be challenged independently as a partial decision.
